I would get a 5 gallon carboy for a secondary. That way you can have a batch in primary and a batch in secondary so you can keep one on deck every 2-3 weeks. I you chose not to use a secondary, then get another primary fermentor.
Having a nice, large stainless kettle with a laminated bottom helps on the brewing side. Mine is 5.5 gallons, heavy gauge stainless with an aluminum-clad base. $70.00 at Wal-Mart. I can do fairly large boils this way, but my electric stove would be maxed out with anything larger.
An immersion chiller is a must have for around 50-60 bucks. Also, some 22 oz bottles speed up bottling as does a bottling bucket.
Buy star-san and PBW in a larger size to save $s. Buy bottle caps in different colors to keep your stock easily identifiable. Buy a Vinator to sanitize with. Try some Whirlfloc tablets. Have a nice beer thief if your primary is a carboy. I bought and LOVE the fermtech unit.
Buy some large opaque bins to store botttles in. Keeps out the sun and prevents a mess if by chance you make a bottle-bomb instead of a brewskie.
buy some smaller bins to kep all your stuff clean and organized.
You didn't mention what you already have, so I am just kinda going over things I have purchased that sped things up as well as made them easier.
Pez.
EDIT" buy an igloo IceCube brand cooler for each fermentor to use as a water bath. Living in Alabama, you will have to keep ferm temps under control. All the brewing specific stuff is available at Midwest, Northern Brewer, and most other places.
